It's will make die for many peoples in the hotter weather

i think you mean greenhouse effect,yes,the climate is much hotter than ten years ago,scientists are anxious about this and doing research on it now. nanjing is a city extremely hot,no matter inside the house or outside,and it will be hotter next month. what can we do?we broke the balance of the nature,now it's our responsibility to get it back.for every single person,increasing the number of plants like trees that take CO2 out of the air is avaiable,and it's not difficult for us,just plant a tree a year,and cut less tress every day.scientists now is focusing on finding alternative energy sources that can replace fossil fuels and so on. i hope their process will be faster.
